7:00 PM Nature – “Kangaroo Mob”
Meet the mob of street smart kangaroos moving into Australia’s capital city and the ecologists following their every move. Over the course of one drought-stricken year we follow mob leader, Black Spot, and kangaroo mother, Madge, with her two young joeys — mischievous Sonny and tiny pouch-bound Alice. Here is a look at what happens when human development encroaches on wildlife habitat and two very different species are forced to co-exist.

8:00 PM NOVA – “Bombing Hitler’s Dams”
In 1943 a squadron of Lancaster bombers staged one of the most audacious raids in history — destroying two gigantic dams in Germany’s industrial heartland and cutting the water supply to arms factories — with a revolutionary bouncing bomb invented by British engineer Barnes Wallis. Wallis and the pilots of 617 Squadron — a lively mix of Britons, Australians, Americans and Canadians — were hailed as heroes and dealt a mighty blow to the German war machine. In this program, NOVA recreates the extreme engineering challenges faced by Wallis and the pilots with the aid of six spectacular experiments. A crack team of experts including dam engineers, explosives specialists, mechanics and aircrew step into the shoes of the Dambusters and attempt to overcome each obstacle in turn.
